· JVASP-79138· CeY3

CeY3 is a rare-earth oxide ceramic compound combining cerium and yttrium in a cubic fluorite-related structure. This material is primarily investigated in research contexts for applications requiring high thermal stability and ionic conductivity, particularly as a solid electrolyte or oxygen ion conductor in advanced energy devices. CeY3 represents a composition within the broader cerium-yttrium oxide family, offering potential advantages over single rare-earth oxides in tuning defect chemistry and thermal properties for demanding high-temperature environments.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
